Features to know about

Brighter and More Efficient Lighting: 4-Diode LED with Amber Reflex Lens

This rectangular LED light puts out bright, clean light while using very little power. With just 0.063 amps drawn at 12.8V, it’s energy-efficient and easy on your trailer’s wiring system. The 4-diode setup gives you reliable illumination that lasts up to 50 times longer than old incandescent bulbs. No fragile filaments or bulb swaps needed—just a steady glow every time you hook up to power.

Built for Wet Conditions: Sonically Sealed and Submersible

You don’t have to worry about water getting in and ruining this light. The housing and lens are sonically sealed into a single waterproof unit, keeping moisture out and protecting the LEDs and circuit board. Whether you’re backing into water or driving through heavy rain, it stays sealed and working like new.

Simple, Solid Mounting: Surface-Mount Design with 2-Wire Hookup

Mounting this light is straightforward thanks to its surface-mount flange. It installs flat against any surface using standard hardware (not included) with 4-13/16" centers between holes. The 2-wire design keeps wiring simple—one power lead and one ground wire, that’s it. At 5-13/16" long x 2" tall x 1-3/16" deep, it fits neatly without cutting big holes or adding brackets.

Built-In Reflector for Fewer Parts and a Clean Look

The built-in reflex reflector means there’s no need for a separate reflective marker on your trailer. It’s DOT compliant and keeps your trailer visible even when the lights are off. That built-in design gives you a clean, finished look while meeting safety requirements with fewer parts to install or maintain.

Durable Construction That Handles Vibration and Heat

Thanks to its surface-mount technology (SMT) circuit board, this light stands up to shock, vibration, and heat better than older designs. The durable polycarbonate housing and amber lens resist cracking or fading over time, so you can count on bright performance season after season.

The Lights are professionally made and still holding up great after a year.. Installed on a Twin Seadoo Trailer.



by:

Just installed them. Really brite. Being sealed and waterproof will solve problem of them getting wet in saltwater



by:

Easy installation and excellent visibility.
Well
made.



by:

Everything went very smoothly. Website very user friendly. The dimensions of lights on the website very helpful with matching my old lights for new LED ones. Fast shipping as well.



by:

These are very nice lights a little bigger than my factory lights. But they covered up the holes perfectly.



by:

They are sturdy and bright! Makes my boat trailer look great!



by:

Great price great product looks and works great on nitro boat trailer.



by:

I ordered these lights to replace the old incandescent lights that corroded from water and dirt infiltration. These lights are much more brilliant than the original incandescent lights they replaced. Hopefully they will also last much longer.



by:

The lights were a perfect match to my existing ones,quick shipping. Great job guys ! !



by:

I am answering for my husband, and as his wife I can tell you he is very happy with his lights. They are already installed.

Anything for his boat/trailer is like jewelry for me (LOL!)

The lights are working perfect. Bright and clearly visible. No problems since installation.



by:

After an order mixup, customer service made everything right. Very pleasant rep and fast service. Highly recommend. New led lights look excellent and are a direct fit replacement on my Prevost Motorhome. Will buy from them again. Price was BETTER than Amazon.



by:

Will use as side turn signal light.
Only
4 LED, not super bright, but very clear and distinct sharp light points, catches attention.
Has 2 pin disconnect on back with plug and two wires.



by:

These marker lights are sharp looking and easy to install. The LED's put out ample light and are very modular in design. Thank you again etrailer for solving my boat trailer re-build.



by:

This LED unit was a perfect replacement in terms of size and mounting hole spacing for the side marker incandescent unit on a 2006 Trailex model 7541 open car trailer that needed upgrading. The grounding wire with grommet made for a easy installation when replacing the single wire unit.



by:

These LED clearance side marker lights were easy to install and light up nice and bright on my trailer. Thanks!



by:

Great service with prompt shipping. Great follow-up to see if I was satisfied with the entire process, which I was.

I relighted our entire horse trailer with the above clearance/running lights last year. The only reason I've ordered more is someone has stolen several of the light off the trailer!



by:

I guess I didn't really read the description well enough, but these things are HUGE... in comparison to the regular amber marker lights I get. If space is a problem, then triple check the dimensions for your application. Other than that, I'm sure they'll glow beautifully, and I love that it's a one piece unit.



by:

I received product in a timely manner when I first ordered it,and now it's been a year of fishing with me launching the boat in and out of salt water. The lights have held up great with no issues.

Three years ago I replaced all my boat trailer lights and installed
the led lights and they are really bright lights for traveling at night.
I have four of the red led on the back of the trailer and you can see
these for a great distance. Makes the trailer very visible at night.
These led lights are the best.
Best Regards
Al



by:

Easy install, mounting hole dimensions matched exactly the incandescent amber OEM Peterson marker lights on our 2004 Lakota 2 horse gooseneck. They bright, low amperage draw.

  • Replacement LED Marker/Clearance Lamps for Peterson PM130 on 1998 4Star Horse Trailer
    We offer a very similar LED clearance/marker lamp that has the same 4-13/16 inch bolt hole spread as the Peterson PM130 lamps you have. For the Red lens, use # MCL76RB or for an amber lens, use # MCL76AB. Both lamps will use the existing mounting holes, so you won't need to drill additional holes. Also recommended is the # A76GB foam gasket to prevent water from getting to the rear of the lamp.

  • Replacing Peterson PM130 Incandescent Trailer Lights with LED Versions
    I will be happy to help you find the right LED replacement lights for your horse trailer. Based on the information you have provided the amber LED replacement is # MCL76AB. The red version is # MCL76RB. Another option is to use Peterson lights # M353A and # M353R. Since lights can sometimes go through design changes the new lights may not have the exact same dimensions as the old lights so that would be why you see slight differences in the measurements between your old lights and these lights.

  • Recommended LED Lights To Replace Peterson PM130
    To replace your Peterson PM130 side marker lights you'll want to use the LED # MCL76RB for red, and # MCL76AB for amber. However I wasn't able to find any pictures of your monarch 5134 lights, so if you can send me a picture of them with some measurements I'd be happy to go over the best LED replacement for those.

  • LED Trailer Clearance Light Recommendation to Replace Peterson PM-130
    Our best option for LED lights to replace your Peterson 130 style lights is the Rectangular LED Trailer Clearance Light, # MCL76AB for amber and # MCL76RB for red. These lights measure 5-13/16 inches long, 2 inches wide, 1-3/16 inches deep, and mounts on 4-13/16 inch centers. As for the ground wire, you will just need to run the ground wire on the light to a clean metal surface. Your current lights are designed to ground through the mounting hardware whereas these are not.

  • What Is Wire Size For Parts And Recommended Connectors
    I called the manufacturers to confirm wire sizes. The Optronics lights, Item # STL9RB and Item # MCL76AB, will have 20-18 gauge wires. The Electric Trailer Brake Kit, Item # AKEBRK-35, will have 12-10 gauge wires. I recommend using the Deka Heat Shrink Butt Connectors. For the 20-18 gauge wires this will be Item # DW05743-10 and for the 12-10 gauge wires it will be Item # DW05745-10. If you need additional wire for your project, Item # 10-1-1 and Item # 10-2-1 are available. I...

  • How Does the Clearance Light MCL76AB Normally Wire Into Running Light Circuit
    Since the clearance light part # MCL76AB that you are interested in is LED it could easily be wired into the running light circuit of your trailer and not cause any problems. What you would need to do is splice the black wire into the running light circuit and then ground the white wire and it would function well for you.
